The demand for high data rate and the inflation in the number of wireless users witnessed unprecedented growth in the past few years and the trend does not seem to flatten in the coming years. Spectrum

scarcity and limited energy resources dictate the need for innovative systems, algorithms and schemes to be included in the future 5G communication standard and beyond. Space modulation techniques (SMTs), or generally called index modulation (IM) techniques, promises significant advantages and attracted significant research interest due to

their remarkable enhancements in terms of spectral and energy efficiencies. In these systems, the indexes of the

building blocks or existing resources are utilized as an extra sources of information that are used to convey additional data bits. SMTs include variant techniques such as spatial modulation (SM), space shift keying (SSK), quadrature spatial modulation (QSM) and their generalization parts. These techniques were investigated widely in

the past few years and many variant schemes were proposed. For instance, non-coherent SMTs are designed such

that they alleviate the need for channel knowledge at the receiver side. Also, non-coherent IM techniques were proposed very recently and transmitter designs with optimum number of hardware components were proposed. The use of these techniques to enhance the performance of variant wireless communication systems in different areas are

also presented recently in literature. For example, SMTs concept is used to develop a multiple access scenario that is

shown to significantly enhances the overall system performance. As well, IM techniques were applied to wireless sensor networks and new communication protocols were suggested. Other attempts applied SMTs to sparse code multiple access (SCMA) and several non-orthogonal multiple access schemes were developed based on the working

principle of SMTs.

The talk will cover the basic working mechanism of these techniques and shed light on recent advances and communication protocols utilizing the basic working mechanism of SMTs and IM techniques. At the end, future directions for promising research studies in these areas will be highlighted and summarized.
